Acne typically appears on your face, forehead, chest, upper back and shoulders because these areas of skin have the most oil (sebaceous) glands. Hair follicles are connected to oil glands.
People of all races and ages have acne. In fact, most people in the U.S. between 11 and 30 years old will be affected by it. Even people in their 40s and 50s can have acne. However, acne most often begins in puberty.
Acne is caused when tiny holes in the skin, known as hair follicles, become blocked. Sebaceous glands are tiny glands found near the surface of your skin. The glands are attached to hair follicles, which are small holes in your skin that an individual hair grows out of.
Acne vulgaris is a common skin condition affecting around 9.4% of the global population.
Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually. Acne usually begins in puberty and affects many adolescents and young adults. Approximately 85 percent of people between the ages of 12 and 24 experience at least minor acne.
Most people have acne on and off for several years before their symptoms start to improve as they get older. Acne often disappears when a person is in their mid-20s. In some cases, acne can continue into adult life. About 3% of adults have acne over the age of 35.
Adolescents and young adults between ages 12 and 24 tend to be the most affected group. It usually begins during the start of puberty, affecting girls earlier than boys. Typically people will outgrow acne but about 12 percent of women and 3 percent of men may still have acne even in their 40s.
Similarly, black students were 18% less likely than white students to report acne of any severity.
Most children and young adults between ages 11 and 30 will have acne at some point. Acne most often begins in puberty. But it can happen at any age. There are different types of acne that affect newborns, infants, younger children, and adults.
Acne is a disease unique to humans and is associated with sebaceous glands that are found at high density on the scalp, forehead and face. Despite being a near universal problem in adolescence, the reason why such troublesome sebaceous glands exist at all is not well understood.
Acne may worsen if you: Get too little sleep. Eat certain foods. Use oily makeup and skin care products.
There's no specific acne gene. However, genetics can play a role in whether you're prone to acne. In addition to genetics, hormones and lifestyle factors can also affect skin and breakouts. No matter what's causing your acne, it can be treated.
According to The Journal of Clinical and Aesthetic Dermatology, 22% of adult women are affected by acne, compared to less than 5% of adult men. Like men, female acne is the result of too much oil being produced by the skin, which results in clogged pores = breakouts.
Our faces aren't used to being covered with a mask, which “increases moisture [and] traps dead skin cells and bacteria on the skin,” added Nada Elbuluk, an associate professor of clinical dermatology at the Keck School of Medicine at the University of Southern California. Another factor is stress from the pandemic.
Most pimples go away on their own, but it may take some time. Deep pimples (pimples under your skin with no head that may feel hard to the touch) may take a few weeks to go away, if not longer.
Although it might feel good to pop a pimple, dermatologists advise against it. Popping a pimple can cause infection and scarring, and it may make the pimple more inflamed and noticeable. It also delays the natural healing process. Due to this, it is usually best to leave pimples alone.
Acne is strongly associated with eating a Western-style diet rich in calories, fat and refined carbohydrates ( 25 , 26 ). Fast food items, such as burgers, nuggets, hot dogs, french fries, sodas and milkshakes, are mainstays of a typical Western diet and may increase acne risk.
Although there were no differences in total number of acne visits across racial/ethnic groups, Hispanic patients were less likely (odds ratio [OR], 0.78; 95% CI, 0.70-0.88) and black patients were more likely (OR, 1.20; 95% CI, 1.09-1.31) to be seen by a dermatologist than white patients in adjusted analyses.
Normal skin is balanced—feeling neither too dry nor too oily. It is not prone to breakouts, flakiness, or feeling greasy or tight. People with normal skin typically have pores that are small, a smooth skin texture, and are less prone to sensitivity or blemishes.
Acne is the most common dermatological diagnosis in non-Caucasian patients. In a community-based photographic study, clinical acne was found to be highly revalent in Black/African American (37%), Hispanic/Latina (32%), and Asian (30%) women, more so than in Continental Indian (23%) and White/Caucasian (24%) women.
Stress can't directly cause acne. However, studies have shown that if you already have acne, stress does make it worse. Researchers have found that wounds, including acne, are much slower in healing when a person is under stress.
Given the increase in oil production, she says your skin will usually look greasier and slightly more inflamed. Zeichner adds that stress acne can also look like a combination of blackheads, whiteheads, red bumps, and pus pimples.
